Support equipment, publications and technical data, personnel training and training equipment and logistics support would also be part of the package.

"The proposed sale will improve Qatar's capability to meet current and future threats and provide greater security for its critical oil and natural gas infrastructure," the agency said in its notification to Congress. "Qatar will use the enhanced capability to strengthen its homeland defense."

The principal contractors for the deal would be the Raytheon/Lockheed Martin Javelin Joint Venture in Orlando, Fla. and Tucson.

Assignment of additional U.S. government or contractor representatives to Qatar wouldn't be required.

The Defense Security Cooperation Agency notified Congress March 26 of a possible Foreign Military Sale to Qatar for 500 Javelin Guided Missiles and associated equipment, parts, training and logistical support for an estimated cost of $122 million.
